IMPROVEMENT IN STEAM-GENERATO RS.

Specification forming part of Letters Patent No. 111,159, dated January24, 1871.`

I, SAMUEL Wnsr, of Elmwood, in the county of Peoria and State ofIllinois, have invented certain Improvements in Steam-Generators, ofwhich the following is a specication:

Nature and Objects of the Invention.

The nature of my invention relates to improvements in the constructionof steam generators or boilers; and the invention consists in formingthe generator in sections, each section consisting of a cylinder, theends of which are vertical and the central portion arched. Twohorizontal cylinders also extend across, connecting, the one thesteam-spaces, and the other the Water-spaces, ot' the vertical parts ofeach section.

Any desired number of these sections are arranged together and boltedsecurely, water and steam connections being provided, and when placedtogether, with the addition of bonnets, the arrangement is such as toafford convenient space for the rire-box and to produce an arrangementof ues which may utilize all the heat and superheat the steam, all ashereinafter fully described.

.Description of thc Accompanying Drawing.

Figure l is a perspective View ot' my improved steani-generator. Fig. 2is a vertical sectional view on the plane ofthe line cc, Fig. 1. Fig. 3is an elevation' ot one of the sections.

General Description.

A A A represent the sections arched, as plainly' shown. B B B and O O Orepresent two series of horizontal cylinders, connecting the verticalparts of each section. D D D D are anges on each section, milled off' toform tight and close connections between the sections. E E are openingsin each section, coinciding or communicating with those in the adjacentsection. These openings are surrounded by tlanges c c. F F are alsoopenings in each section, coinciding and communicating with those in theadjacent section and surrounded by lian ges f f f.

The sections A A A are brought together and secured by bolts G G Gpassing through each of the apertures E, E, and F, upon which is placeda cap, g', and nut g".

H is a bonnet, connecting the lues at their return ends. H is also abonnet, connecting the flues at their return ends. I I are plates,

covering the elevation of the end sections. J is the furnace-door; j,the grate, and j the ash-pit. K is the chimney. L L are supports.

Any desired number of the sections A A may be brought together andsecured by the bolts G G G, provision being made by suitable packing andsimple appliances for insuring a perfect joint between the sections andthe avoidance of any leakage from the opening through which theycommunicate with each other.

The sections A A A being connected at their bases by the apertures E E,and at their tops by the apertures F, the desired circulation isprovided for within the sections.

The water-line should be kept within the horizontal pipes B B B, leavingample steamroom above.

When the sections are placed in position the spaces between theirdifferent pipes will form the fines, as shown plainly by Fig. 2, inwhich the direction of the arrows shows the course of the ilame and heatfrom the lire-box to the chimney.

This generator is adapted more particularly to producing steam forcooking purposes, especially for cooking feed for animals. It may,however, be used to advantage for producing power by simply making theparts strong.

The heat passing around the steam-room, in the upper part ot' thesections, will superheat the steam and deliver it dry for culinarypurposes.

Claims.

I claim as my inventionl. A steam-generator composed ot` sections A A A,when constructed substantially as described, with crosspipes B B B and CC G and arched top, and provided with steann connections F andwater-connections E E, and secured by bolts G G G, substantially in themanner and for the purpose specified.

2. The sections A A A, constructed as de scribed, and secured by thebolts G G G, when combined with the plates I I, bonnets H H, grate j,door J, chimney K, and supports L L, substantially as described, and forthe pur pose specified.
